io.github.palexdev.virtualizedfx.flow.simple.SimpleVirtualFlow<T,C>

类型参数:

T - the type of objects to represent

C - the type of Cell to use

所有已实现的接口:

VirtualFlow<T,C>, Styleable, EventTarget

public class SimpleVirtualFlow<T,C extends Cell<T>>
extends Region
implements VirtualFlow<T,C>

Simple implementation of VirtualFlow.

This VirtualFlow creates Cells of type Cell, it's features are:

- The items list is managed automatically (insertions, removals or updates to the items)

- The cell factory can be changed any time

- Can show the cells from TOP to BOTTOM or from LEFT to RIGHT, this is the orientation property

- It's possible to change the orientation even at runtime (but it's also recommended resizing both the VirtualFlow and the cells)

- It's not necessary to wrap the flow in a scroll pane as it already includes both the scroll bars

- It's possible to set the speed of both the scroll bars

- It's possible to scroll manually by pixels or to cell index

- It's possible to get the currently shown/built cells or a specific cell by index

The cells are contained in a Group which is a SimpleVirtualFlowContainer.

initialize

Adds the container to the children list, calls setupScrollBars().

Also adds listeners for the cellFactory property and the orientation property. Also initializes the orientation helper and the container when Parent.needsLayoutProperty() is becomes false.

A little note: the orientation helper is initialized manually at this specific point because otherwise the added listeners cause an infinite loop that will eat RAM for some reason.
